I have a banks non-wastegated turbo ready to install and was curious how much I need to open up the exhaust for the best benefit. the banks has a 3" downpipe which is nice but is 4" beneficial at all to 3" behind the downpipe?
regardless I plan on removing the muffler so it'll be free-flow. Just don't know enough about back pressure and the IDIs.
Thanks.
